Abstract
A low power SAW stabilized monolithic microtransmitter has been developed. This new device replaces all of the RF circuitry in a low cost transmitter, such as the ones used in wireless security systems. This device makes it possible to meet FCC specifications without costly design iterations. The oscillator in the transmitter is controlled by a third generation SAW resonator which eliminates the need for impedance matching or phase shifting networks in the signal feedback path. This unique type of resonator made the monolithic transmitter design possible. The theory of operation, system architecture, and performance will all be presented in this paper.
